title: 5-Cyclo-hexyl-2-(2-fluoro-phen-yl)-3-methyl-sulfinyl-1-benzo-furan.
abstract: In the title compound, C21H21FO2S, the cyclo-hexyl ring adopts a chair conformation. The 2-fluoro-benzene ring makes a dihedral angle of 38.68 (6)° with the mean plane [r.m.s. deviation = 0.018 (2) Å] of the benzo-furan fragment. In the crystal, mol-ecules are linked by pairs of C-H⋯O hydrogen bonds into dimers, which are further packed into stacks along the c axis by C-H⋯O hydrogen bonds. In addition, the stacked mol-ecules exhibit S⋯O contacts [3.1733 (13) Å] involving the sulfinyl groups. The F atom is disordered over two positions, with site-occupancy factors of 0.961 (3) and 0.039 (3).
